For warm and dry days ok. At freezing temps in the one digit F area - those gloves are defintaely not warm enough, this is already mentioned in the description. but when it rains or the snow is very wet after half a day of riding the do get humid inside (and i am sure i was not sweating at my hands...).
they adjust very well to chaning light conditions. when the sun is away you really see the differences in snow surface that lies before you. helps a lot to keep up the speed while boarding even when the light gets dimmer.
